Thanks, Yes the filter is a non cleanable part so it was replaced as indicated. There is no detectable air leak, at least at the filter, as the center o-ring seal has been checked and double checked. An electric fuel pump was installed for a short time inline prior to the fuel filter so there was no low pressure area at the filter during that time to cause a air leak. No other fuel leaks were detected either as would have been the case with 70-80 of fuel pressure from the electric pump. A clear fuel hose has been placed on the outlet end of the filter housing to monitor both for fuel quantity and air bubbles. Immediately after power failure fuel line was checked...No air bubbles and full of fuel. I have pulled the tank twice in the recent past to check for obstructions in the pickup area. And the fuel filter was changed twice within a two week period. This is in addition to the cleaning of parts listed above.
Can anyone tell me how common a true MAP sensor failure is? Other than being dirty and a good cleaning won't cure? While I have not gotten a MAP sensor code, I have heard that it can cause both the 401 and 299 codes I do have. Additionally, I did buy a code reader, Digital OBD II car reader. While pulling the codes and determining what the codes mean is not difficult, it is supposed to run diagnostics from the cars computer, but I have not figured out how to do that. I guess I will have to call the Manufacture, but any tips there would be helpful and appreciated! Thanks all. I feel like
